-This invention relates to an improved spparrot-us for the treatment of yarns, or other similar mater-ibis, in the operation of clean' 'ing, boiling, bleaching, dyeing, oxidizing,

fixing", developing, etc; and further, this invention rclstes more particularly to that type apparatus TQCGGDIZGG by those versed inthe :irt e boom dyeing nuu'hine, Where-- in the material to be tolrcn under treatment is first warped or Wound upon a yarn beam and is thence placed in the machine for trentment, from whence it is taken for treatinent by the sizer or shisher.

time of the most important objects oi the present invention is to provide a, machine of the oboveenentioned type wherein the treatmerit of the yarn, or other material, is per termed in rapidly succeeding; steps, thereby insuring uniformly dyed product, free from spots orother discolorotions it further very important object of our invention resides in the provision of an apperotus of this class wherein the yarn is immersed. by subnierging the beam by the introduction of the dyestuft at the bottom oi it vat contuinine 2i vertical boom. Wound with yrtrn, the dye-stui't' being fed in both from Within. and Without the beam.

A still further in'iportont object ofour involition; resides in the manner of expelling till the dytstuii' from the vet and beam, and simultobeously producing oxidetion of the dye-stud, impregputing the beam as the main body oi dycstuft' recedes, thereby insuring ii uni'lorn'i oxidation of the dyestoit iinpregnstiog the yarn. Y

lit may be here mentioned that while this zippzn'etus is cdzipted for the many treat-- ments hereinbefore referred to, it is more particularly adapted to carry out the steps oi? the process set forth in our co-pendmg application tiled in the United States Patent Oilice the 29th day of llloy, i915, and beer illustratinc the circulating system.

ing the Serial Number 31275, and entitled process of dyeing yarn.

"llith the above and other objects in View,"

the invention consists in the construction and combination of parts illustrated in the accompanying drawings and hereinafter specifically described, it being understood that various changes in the irm,;prop0rtions, and other minor details of construction, may be resorted to in actual practice, without departing from the spirit and scope of the invention.

In the drawings, wl1ich,-as above stated, are typical of one form of the apparatus, and particularly illustrates form which we have found in actual practice to give good results:

Figure 1 is a central section elevation-view through the apparatus.

Fig. 2 is a transverse section through the the line 2-2 of Fig. 1.

3 is a plan View of a portion of the cover locking mechanism.

Fig. i. is a crosscnt section View of a portion of the Wall of the reticulated beam used in connection with this apparatus.

'75 apparatus; the plane of this section being Fig. is a diagrammatic perspective View in detail The apparatusillustrated comprises the vertical vet 1 of cylindrical form to receive and contain a beam 2 during the treatment operation, and itis upon this beam that the yarn, or other material, undergoing treatment is warped or Wound, asindicated by the dotted lines at 3. I

The beam 2, preferably of that type illustrated in our co-pending application filed-in the United States Patent Oilice March 3, 1.915, and bearing the Serial-Number 11727, this application being entitled A yarn body 4 huving ends 5 end 6.. the lower one being aper'tured as at 7 to admit the dyestuli to the interior of the beam, whereas the upper one is provided with an airrelief cock 8 for purposes to be hereinafter set forth.

The lower end member 5 of the beam 2 must make e steam tight joint with the bottom of the vet 1 and must be positioned di rectly over a port 9 in the bottom of the vat. in order to hold the beam 2 in this position a cross bar 10 is provided which engages beam, principally consists of a reticulated cover 1 1 and a superposed rotatable plate the vat outside of the beam 2.

providedwith angular slo'ts which, upon the rotation of the plate 15, simultaneously move a plurality of locking members into and out of a locking position as the case may be.

- The locking members are illustrated at 16 and may be tightened in the locking position by hand-wheels 17.

At the bottom, the vat 1, as before stated, is ported at 9.and this port communicates with the interior of the beam 2 through apertures 7 in the bottom end thereof. The bottom of the vat 1 is also apertured exteriorly of the beam as at 18 to communicate with The-circulation system comprises a tank 19 for containing a quantity of dye-stuff in fluid form, and'leading from the bottom of this tank is a pipe 20 which connects at 21 with the suction end of a centrifugal pump 22, and further has a branch 23 leading to a water supply. The branch23 is controlled by a valve 24 and the outlet 20 is controlled by a valve 25. Thus either water or fluid dye-stud may be fed to the pump 22.

In order to drain the vat 1 and tank 19, a

valve 26 is located adjacent to a T 27 in the pipe 20 and is in connection with the latter,

and a pipe 28 leads therefrom to-the sewer.

Immediately adjacent the T 27 and between the pump and said T is located a valve 29, and if this valve 29 is closed and valves 26 and 25 are opened, the tank 19 may be drained. From thev discharge end of the pump 22 leads a pipe 30 which has its outlet end 31 turned into the tank 19. In the pipe 30 are located two valves 32 and 33, the.

former being immediately adjacent the pump discharge outlet, and the latter adjacent the outlet of the pipe 30. Intermediate of the two valves 32 and 33 are located two PS 31 and 35 which, lead to valves 36 and37, connecting with pipes 38 and 39, the former entering the port 9 .and connnunicating through apertures 7 with the interior of the beam 2, while the latter enters the port 18 and is in communication with the vat 1 exteriorly of the beam In connection with 'the two pipes 38 and 39 are other pipes 40 and 41, respectively, which lead to valves 42 and 43 connecting with TS -11 and 45 in the pi e 20 and located between T '27 and va e 25; I

By this arrangement the fluid dye-stufl' contained within the tank 19 may be circulated from without the beam 2 to within the beam, or vice versa. For instance, by opening the valves 25, 29, 32, 36 and 37, the dyetion, the-tank and beam are filled in the manner above set forth, and the air cock 8 is then closed, consequently no air remains within the beam. The cover 14 is then placed in position and to continue operations the dyestufi' is circulated from without to within the beam by closing all of the valves and then opening valves 12, 29, 32 and 37. After this circulation or agitated How of liquid has taken place for a suitable length of time,

I these valves are closed and a flow of dyestutf is induced from within to without the' beam by opening valves 43, 29, 32 and 36. It will thus be seen that by suitablycontrolling the valves ubOVBjHBIllZlODQd thefluid dye-stuff or other treating agents may be circulated in either direction through the beam, thereby thoroughly impregnating the yarn wound thereon.

In using'oxidizable dyes such as indigo dye liquor or stuff it is found to be desirable to follow the dye liquor up with'a volume of air; as the liquid recedes from the yarn oris withdrawn from the apparatus. Unless this is done the yarn will be spotted, since it is the air that completes the coloring of the yarn by chemical oxidation-of the dye liquor absorbed by theyarn. In order to accomplish this, an air inlet 46 is provided adjacent the top of the vat 1, and connects with an air supply 47 which also has a branch 48 entering the pipe 30 beted at the inlet 46 the air will'course through the beam 2 and out the bottom thereof driving the unabsorbed dye liquor with it and following up the receding dye liquor by the oxidation of the dye liquor impregnating the yarn, thereby insuring an even oxidation through and through the yarn and a consequent uniform spotless coloring of the yarn. By the arrangement of the air pipe system it is also evident that by manipulating the battery of valves in connection with the circulation system, the air may be circulated in the same manner as the dye-stuff. Also by reason of the water'inlet 23 at the end of pipe 20, wash water may be circulated in the same manner tween T 35 and valve 33. If air beadmit- I through the yarn,

as the dye-stuff. Furthermore; it is known to be desirable at certain stages of the dye ing process, to circulate steam within the rat or beam and to provide "for this a steam inlet ithis provided which is tapped into the pipe 30 between Ts 3i and 35, and still further it'is hnown to be desirable during certain stages of the dyeing process to utilize dry heat and for this purpose a heating coil 50 surrounds the beam at the bottom. thereof and isconnected with a steam supply 51 and discharges through the open end 52.

it will be seen from the apparatus herein before set forth that thorough treatment of the yarn or other material wound on the beam 2, with a cleansing agent, bleaching agent, or dyeing agent, may be accomplished by arranging for the circulation of the various agents and accessory agents such as steam and air, in various directions and by such circulations an agitation is produced in. the medium circulated which keeps all solid matters suspended in. the solution. utility in carrying out indigo dyeing wherein the dye is oxidized, lies in the fact that the dye-stuff to be oxidized is oxidized by the agent which, under pressure, drives the superfluous dye-stuff out of the material and out of the rat and beam, following up the dyestuft as it recedes.

From ncction with the accompanying drawings, it will be evidentthat an apparatus admirably suited for the purposes herein set forth has been constructed; Also it will be apparent that a battery of tats may be ar- The particular versing the How the foregoing description in conranged to be operated in connection with a single circulatory system andbat-tery of valves such as that indicated. and also that a plurality d't beams may be arranged for trvatmmit in a single vat.
